I would agree with you if the long name causes the expressions hard to
read. In this particular case, it is just the single parameter to the
mutex_lock() and mutex_unlock() functions. There is no confusion and
overly long lines. So I think it is OK. In fact, I got the opposite
advices in the past that some people prefer long descriptive names than
short and cryptic names.
Cheers,
Longman
